Intelligence CATV

The article describes information network and CATV applications, backbone network structure. Cable is a natural network for carrying high-capacity, bandwidth - intense information. In the age of analogue program signals, cable´s capacity was a natural transmission media for broadcast calor TV and high-fidelity stcreo sound programs. In the new digital program signal age, cable´s high capacity is a natural network for carrying interactive computer-based. data - intensive multimedia programs. When designing and configuring an ATRI / based broadband CATV (B-CAW), it remains difficult to guarantce the quality ofscrvicc (QoS) for differenl service classes, while still allowing enough ststistical sharing of bandwidth so that the network is efticicntly utilized. This article describes the main challcngcs ofimplementing an end-to-end architecture for delivery of high-quality, IP-based residential TV sewices to residential customers. The main ehallengcs met while implementing the IP-based ai-chitecturc are competitive positioning relative to traditional CATV architectures, ov~rnlal rchitecture, herd-end architecture and quality issues, traffic enginccring for stringent QnS rcquircments, IP multicasl requirements, and business case considerations,
